When I scrub the footage, premiere jumps around the time line in large gaps. I might get 1-3 frames for every minute of video when moving the mouse/cursor at a reasonable rate. It makes previewing my footage almost impossible. I basically have to let the clip play in realtime to see what's on it.

I expect the scrubbing to be smooth. Like I see in all the training material I have been watching.

Not sure what MPE RT is? Mercury Playback Engine...Real Time?

I'm also having issues with certain features when creating titles. Such as: slow feedback when changing the "degree" of the text (it takes sometime for the degree number to change onscreen...basically jumps around). When scrubbing the linear gradient option, I'm also seeing some lagging. I've circled the areas in RED on the image below:

How do you bring the AVCHD files into Premiere? When transferring data from camera memory card to PC hard drive, copy the WHOLE FOLDER STRUCTURE to drive as is, then use Media Browser in Premiere to import clips. Next, silly question, but have you "zoomed in" to the timeline before scrubbing? Use the + and - keys. Get in closer for finer scrubbing response, viewing just a smaller part of the timeline rather than everything at once.

As Jim and I have both said, it is important to copy over ALL the folders intact. If you try to dig down in the camera card and only copy the video files, that is where problems come up. Copy the whole works to your hard drive, and then at the lower left of Premiere interface, next to Effects Tab, look for the Media Browser tab there, and Import the clips that way.

AVHCD uses a lot of extra info in the various folders, sometimes having seperate audio even, and all the extra files have some meaning and importance. Media Browser understands all of that and once you point it to the parent directory it will sift through it all and properly import any relevant files and their connections to one another, behind the scenes. This is best practice for file-based media imports.

Well, I shot some new footage and copied the entire PRIVATE folder over. Then used Media Browers to import the files. Still having the scrubbing issues. Also have choppy video playback. The clips playback fine in WMP, but as soon as Premiere gets ahold of them, ick...

Well, you effectively have only two disks/volumes, which is below practical minimum requirements. A player like WMP demands much less of a system than an editor and you are running into disk setup limitations. It is a pity, because your CPU is quite good, but your disk setup is not. Add a couple of disks...

Very unlikely. AVCHD has the same data rate as DV, and even a single modern disk is plenty fast enough to feed multiple simultaneous streams.

Even with a single track with AVCHD material, it requires a sustained transfer rate of up to 50 MB/s and with 3 or 4 tracks that figure easily goes up to more than 95 MB/s sustained transfer rate, with 4K material it goes beyond 300 MB/s. Add the half duplex nature of SATA into the configuration on a system with only two disks, the Windows housekeeping, the memory requirements which are way more than 14 GB and the need for paging and you are lost.

Sorry chap, you really have to get more acquainted with the intricacies of decoding AVCHD material before you make such blanket and incorrect statements.

And this is only playing the timeline, not scrubbing it, which makes for much heavier disk requirements.

A mirrored raid is still seen as a single volume by Windows. There is nothing wrong with a raid1, it helps you keep your data safe, but it is costly and offers no performance gains over a single disk. If you have a look at the 'Featured Discussion' at the top of the hardware forum about Raid Performance and Rebuild issues, things may become a bit clearer.

Kid, don't let Harm bambozle you. Your computer is plenty fast to scrub AVCHD. And you were correct in guessing that the problem was with CS5.5. There are a number of threads here that talk about the problem. Adobe has not addressed the problem (and, no, CS5.5.2 did not correct the problem). If you can get a hold of a copy of Premiere CS5, give it a try. Scrubbing will be as smooth as butter with AVCHD. My guess is scrubbing the same material with some other editing software will be as equally smooth. I've got a computer that has a fraction of the power of your computer. DSLR footage and AVCHD is slow and choppy in CS5.5. But in CS5, no problems at all. Scrubbing is as smooth as glass in CS5. What adobe did between CS5 and 5.5 I have no idea, but the problem hasn't been fixed. And of course there is no guarantee it will be fixed in CS6. Hell, they may move onto CS10 before they get around to fixing the issue (which is par for the course for adobe).

Just trying to save you some grief, kid. Nothing wrong with your computer, it is CS5.5. Hope you read this before the moderator deletes my account.

Because it was redundant. Just like the two that I'm about to delete now.

You made your point in the post replying to RByds4te. You don't need to repeat the same info in replies to other participants. Stephen and Harm will see your reply to RByds4te when they check the thread, either here or by email. They don't need their own personal copy.

I am aware of the other posts and am a bit concerned that Adobe has not addressed this issue. I would very much like to get a copy of Pre Pro Cs5, but I cant (in my right mind) spend another $500 on premiere.

Perhaps Adobe would be willing send me a copy (or download) of Cs5, so that I can test this out?
